COMPUTER-BASED SYSTEMS AND METHODS INVOLVING BIOMETRIC AUTHENTICATION ASPECTS FOR HANDLING EXCEPTIONS, ENABLING DEACTIVATION AND/OR PERFORMING OTHER FUNCTIONALITY

Systems and methods involving biometric authentication of transaction cards including aspects of exception handling, deactivation and other features are disclosed. In one embodiment, an exemplary computer-implemented method may comprise generating a first user interface having a plurality of interactive UI elements that enable a card owner to manage a plurality of features associated with a transaction card, and determining, if a biometric-activated control is enabled and the vendor is not excluded from the biometric-activated control, whether the transaction card is biometrically-active. Further, the plurality of interactive UI elements may include a first UI element that is configured to allow the card owner to enable a biometric-activated control of the transaction card, and a second UI element that is configured to allow the card owner to exclude one or more vendors from the biometric-activated control.
